Poverty is a problem in all countries: relative poverty is nit, its just BS. As for starvation in the capitalist west, who are you kidding? Obesity seems to be killing more people than starving to death.
However, to deal with poverty it is not necessary to destroy the capitalist society, it is simply a matter of making available to the offspring of the poor all the opportunity that good health, housing and education can obtain. And all these are paid for through successful GDP. And that comes from capitalism. Ask any North Korean if you're not sure.
